Note: Conan will skip the generation of the ``CMakeUserPresets.json`` if it already exists and was not
generated by Conan.

.. note::

By default, the version schema of the generated ``CMakeUserPresets.json`` is 4 and the schema for the ``CMakePresets.json`` is 3,
so they require CMake >= 3.23.
You can control the version of the generated ``CMakePresets.json`` and ``CMakeUserPresets.json`` with a :ref:`configuration<conan-cmake-toolchain_conf>`
``tools.cmake.cmaketoolchain.presets:max_schema_version``.

It can be set in the `global.conf`, with `-c` in the :command:`conan install` command, or in a profile.
The minimum accepted value for this conf is ``2``:

.. code:: bash

conan install . -c tools.cmake.cmaketoolchain.presets:max_schema_version=2

The version schema of the generated ``CMakeUserPresets.json`` is 4 (compatible
with CMake>=3.23) and the schema for the ``CMakePresets.json`` is 3 (compatible with
CMake>=3.21).
